ENGIE is one of the nation's leading independent power companies that thousands around the country rely on for energy every day. David King is a service technician, working to install service breakdowns or administration quoting, and says that his work day is drastically improved by his Testo 557 digital refrigeration gauge – here's how. 

The type of equipment used to get the job done 

ENGIE has a commitment to a sustainable future, delivering energy via renewable, gas-fired and brown coal-fired generating plants in Victoria, South Australia and Western Australia. This means they supply 12 per cent of Australia's National Energy Market. With so many relying on their service, technicians like King have a lot of pressure on their shoulders to get accurate and efficient measurements.

To do this, King works with a range of instruments from basic hand tools to shifter, drivers and drills and temperature gauges. However, when it comes to service and maintenance work, nothing quite compares to the digital tools.

The other plus with digital is that you don't have to guess your temperatures and pressures, you can just look and they're there and they're accurate.

"There's obviously a big difference between the digital and analogue tools. Digital is a lot more accurate and you can actually see when a system is losing refrigerant or if you're pressure testing you can see when the pressure has dropped. Analogue takes a lot longer to see that you have a leak. The other plus with digital is that you don't have to guess your temperatures and pressures, you can just look and they're there and they're accurate."

David has been working with digital for about five years, but of all the tools he's worked on he says Testo is the number one on the market

Using the Testo 557 to improve the job

The Testo 557 helps ENGIE stay on top of service and measurements. The Testo 557 helps ENGIE stay on top of service and measurements.

The Testo 557 digital refrigeration gauge makes the technician more aware of the systems they're operating on, explained King.

"The tool is time-saving, you can walk up to a job, put your gauges on and you have instant temperatures and pressure. Readings are both faster and more accurate. You can change it for your colleagues who are used to working in different measurements as well," said King. 

Specifically, the two NTC thermistor clamp probes provide technicians with superior accuracy, real-time superheat and sub-cooling readings. The wireless Bluetooth connection sends the measurement data right to your smartphone so you can quickly and efficiently document the job. It can store up to 60 refrigerant profiles right in the instrument, and the app can download new refrigerants right into the digital manifold.
